It is ideal for 1.65 to 5.5 VCC operations and low power and low noise applications. The internal circuit is composed of 3 stages including buffer ) (s t c u d o r SOT23-5L u d o r P e ORDER CODES PACKAGE t e l o SOT23-5L SOT323-5L ) s ( ct SOT323-5L T&R 74LX1G70STR 74LX1G70CTR s b O output, which provide high noise immunity and stable output. Power down protection is provided on input and output and 0 to 7V can be accepted on inputs with no regard to the supply voltage. It can be interfaced to 5V signal environment for inputs in mixed 3.3/5V system. All inputs and outputs are equipped with protection circuits against static discharge.
